Happiness itself is sufficient excuse. Beautiful things are right and true; so beautiful actions are those pleasing to the gods. Wise men have an inward sense of what is beautiful, and the highest wisdom is to trust this intuition and be guided by it. The answer to the last appeal of what is right lies within a man's own breast. Trust thyself.
Wise statesmen ... established these great self-evident truths, that when in the distant future some man, some faction, some interest, should set up the doctrine that none but rich men, or none but white men, were entitled to life, liberty and the pursuit of happiness, their posterity should look up again at the Declaration of Independence and take courage to renew the battle which their fathers began.
Let no person think lightly of good, saying in his or her heart, "it will not benefit me." As by the falling of raindrops a jar of water is filled, so the wise person becomes full of good, even though he or she collects it little by little.
At first he who invented any art that went beyond the common perceptions of man was naturally admired by men, not only because there was something useful in the inventions, but because he was thought wise and superior to the rest. But as more arts were invented, and some were directed to the necessities of life, others to its recreation, the inventors of the latter were always regarded as wiser than the inventors of the former, because their branches of knowledge did not aim at utility.
Therefore it is most expedient for the wise, if Don Worm (his conscience) find no impediment to the contrary, to be the trumpet of his own virtues, as I am to myself.
Let the wise guard their thoughts, which are difficult to perceive, extremely subtle, and wander at will. Thought which is well guarded is the bearer of happiness.
Gentlemen, let us suppose that man is not stupid. (Indeed one cannot refuse to suppose that, if only from the one consideration, that, if man is stupid, then who is wise?) But if he is not stupid, he is monstrously ungrateful! Phenomenally ungrateful. In fact, I believe that the best definition of man is the ungrateful biped.
